Erratum to: Chuan Lai, Xiaogang Guo, Jian Wei, Bin Xie, Like Zou, Xiaolong Li, Zongxin Chen, Changmao Wang, Investigation on Two Compounds of O, O’-dithiophosphate Derivatives as Corrosion Inhibitors for Q235 Steel in Hydrochloric Acid Solution, 2017, 15, 263-271, 10.1515/chem-2017-0034
The original version of the article was published in Open Chem. 2017, 15 (1) pp. 263-271. Unfortunately, the original version of this article contains mistakes in the caption of the y-axis of Figure 1 and 7. Additionally, the actual units of the charge transfer resistance should be Rct (Ω cm2), not Rp (Ω cm -2). Corrected versions of the Figures and Table are presented below.
Infrared spectra of Inhi-Ph and Inhi-BrPh.
Langmuir adsorption isotherm for Inhi-Ph and Inhi-BrPh on Q235 steel in 1.0 M HCl at 30°C.
The electrochemical parameters of impedance and the corresponding inhibition efficiency of Q235 steel in 1.0 M HCl with various concentration of Inhi-Ph and Inhi-BrPh at 30°C.
